Study Summary
The standard approach to managing chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) is to wait until you have symptoms before treatment is given. The goal of this clinical research study is to learn if providing earlier treatment for CLL or SLL with ibrutinib in patients who do not have symptoms will be more effective than waiting until symptoms develop. This is an investigational study. Ibrutinib is FDA approved and commercially available for the treatment of patients with CLL or SLL. It is considered investigational to give ibrutinib to CLL and SLL patients before symptoms develop. The study doctor can describe how the study drug is designed to work. Up to 50 participants will be enrolled in this study. All will take part at MD Anderson.
